GE Fanuc URSHA UR SHA Multilin Power Supply Module

Overview

The GE Fanuc UR-SHA (UR SHA) Multilin Power Supply Module is a third-generation power supply module designed for use with the Universal Relays series of products. It provides power to the relay and its dry contact input connections, functioning as one of the high power modules within the series. The UR-SHA delivers a nominal power rating of 125 to 250 V, distinguishing it from lower power modules that supply 24 to 48 V (DC only). Users must ensure that the power supply meets system requirements, as exceeding recommended ratings may damage the system.
